I have a 2009 wrx with around 68k miles. I recently put on a cobb intake, acessport and downpipe. I started to notice a serious problem which my local tech told me it could be something major. So took off all the aftermarket parts and flashed it back to stock. I brought it to the dealership because i still have a extended warranty.
Alittle concerned they might question somethings and possibly void the warranty. Could they tell its been flashed? Do you think they could give me problems?
